CVE-2019-14718
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVerifone MX900 series Pinpad Payment Terminals with OS 30251000 have Insecure Permissions, with resultant svc_netcontrol arbitrary command injection and privilege escalation.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Verifone MX900 series pinpad payment terminals running OS 30251000 have insecure file/system permissions that allow unauthorized access to the svc_netcontrol service. This service contains a command injection vulnerability that can be exploited to execute arbitrary commands with elevated privileges, enabling a local attacker to gain full control of the device.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device modelCheck if the device is a Verifone MX900 series pinpad terminal. This can typically be done via physical inspection of the device label or through device discovery/network inventory that reports the device model.Affected if Device is not a Verifone MX900 series terminal - not affected by this specific CVE.
-
Check firmware versionAccess the terminal's diagnostic or admin interface and retrieve the firmware version. On the MX900, this is typically shown as 30251000 in the system information or version display screen.Affected if Firmware version is exactly 30251000 - this is the affected version.
-
Verify svc_netcontrol service accessibilityAttempt to access or communicate with the svc_netcontrol service on the terminal. This is typically done through the device's service port or network interface if exposed.Affected if The svc_netcontrol service is accessible from an unauthorized network position or local unprivileged account.
-
Check file permissions on serviceIf you have administrative access to the terminal, inspect the file permissions on the svc_netcontrol service binary and its configuration files. Look for world-readable or world-writable permissions that should not exist.Affected if File permissions on svc_netcontrol are overly permissive (e.g., world-readable/writable).
-
Look for signs of command injection exploitationReview any available logs on the terminal for suspicious commands or unexpected network connections. Check for new or unexpected processes, scripts, or network connections originating from the terminal.Affected if Evidence exists of unexpected command execution, new files, or unauthorized network connections originating from the terminal.
A user is affected if they are running a Verifone MX900 terminal with firmware version 30251000 and the svc_netcontrol service is accessible without proper authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-provided firmware/security updates from Verifone to address the permission and command injection issues. Restrict physical and network access to payment terminals to minimize attack surface.
